IMPROVEMENT IN WEATHER-STRIPS.

Specification forming part of Letters Patent No. 13l,430,'datedSeptember 17, 1872.

To all whom it may concern:

Be it known that we, HENRY DIERKEs and HERMANN BUSSMANN, of Syracuse, inthe county of Onondaga and in the State of New York, have inventedcertain new and useful Improvements in Weather-Strips; and do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawing making a partof this specification, in which- Figure 1 is a front elevation of a doorhaving attached to its lower edge our improved device. Fig. 2 is avertical central section of the same on the line a: as of Fig. 1. Fig. 3is a plan view of the lower edge of the door with the hinged portion ofthe weather'strip removed. Fig. 4 is a plan view of the lower side ofsaid weather-strip complete and detached from the door. Fig. 5 is apartial edge view of the door as closed, showing the weather-strip andits closing stop and Fig. 6 is a plan view of the door swung partiallyopen, vfvith the frame removed, upon the line 3 y of Letters of likename and kind refer to like parts in each of the figures. I

Our invention is an improvement upon a weather-strip for whichapplication for Letters Patent was filed October 16, 1871 and itconsists in the combination of sliding hinges with the vertical swingingportion of the device, substantially as and for the purpose hereinafterspecified.

I In the annexed drawing, A represents a strip of wood or other suitablematerial having the form in transverse section shown in Figs. 2 and 5,and so secured to or upon the outer face and near the lower edge of adoor, B, as that its fluted portion shall be uppermost and its rabbetedportion in front and downward. Within the rabbet a, or upon its nearlyvertical face, is secured a strip of metal, 0, which corresponds inlength to the length of the strip A, and extends downward somewhat belowthe lower edge of the same. Hinged to or upon the lower front edge ofthe strip Ais a second strip of wood, D, having the form shown in Figs.2 and 3, which extends downward and forward, so as to bring its loweredge upon a line horizontally with the lower edge of the door and causeit to pass immediately over the sill E whenever said door is closed. Inlength the hinged strip D corresponds to the length of the fixed stripA, and each to the space between the upright portions F of the frame;but in order that said hinged strip may conform to the varying relativepositions of said frame and door as the latter is opened or closed, thehinges d are so constructed as to permit their leaves to move a certaindistance longitudinally upon their axial rods, by which means acorresponding movement of said hinged strip is obtained. A spiralspring, G, having its ends connected to or with the fixed and hingedstrips, draws the latter longitudinally toward the hinged edge of thedoor, while a flat spring; H, attached to said fixed strip and extendingdownward and forward, with its free end bearing against the rear side ofsaid hinged strip, presses the latter forward and upward. i

As thus constructed the operation of the device is as follows: Uponclosing the door the inner egg]. of the hinged strip strikes against thecorrespondingjamband is forced endwise upon its hinges until itsopposite end passes within its jamb, after which a stop I, seen in Fig.5, arrests the forward movement of said strip and forces it downwarduntil its lower edge rests upon the outer or lower portion of the sill,by which means the space 'between the lower edge of the door and thesill is closed and the inward passage of air or water effectuallyprevented.

The especial advantages obtained by this attachment of the movable stripis that it enables the employment of wood instead of metal, as in thedevice heretofore named.

Having thus fully set forth the nature and merits of our invention, whatwe claim as new In combination with the fixed strip A and movable stripD, the sliding hinges (1, substantially as and for the purposespecified.

In testimony that we claim the foregoing we have hereunto set our handsthis 8th day of January, 1872.
